Compression Modulus and Symmetry Energy of Nuclear Matter with KIDS Density Functional

Equation of state dense nuclear matter is explored in the KIDS density functional theory. Parameters equation which are coefficients energy expanded powers $(\rho - \rho_0)/3\rho_0$ where $\rho$ and $\rho_0$ its at saturation constrained by using both data mass-radius relation neutron star determined from modern astronomy. We find that combination can reduce uncertainty parameters significantly. confirm newly reproduce basic properties spherical magic nuclei with high accuracy. Neutron drip lines, on other hand, show non-negligible dependence symmetry energy.
